Description
Explosionssperre für den Untertagebergbau Die Erfindung bezieht sich auf eine Explosionssperre für den Bergbau zum Einbau in Strecken unter Tage, die als Sperrmittel in Tröge gefülltes Wasser und ein zweites Löschmittel enthält.Blast Barrier for Underground Mining The invention relates to on an explosion barrier for mining for installation in underground routes that contains water filled in troughs as a barrier and a second extinguishing agent.
Als vorbeugende Maßnahme ist bekannt, zur Verhinderung von Kohlenstaubexplosionen wäßrige Lösungen hygroskopischer Salze, z. B. Chlormagnesium oder Chlorealcium, unter Zugabe geringer Mengen eines Netzmittels in derartiger Form im Wetterstrom zu vernebeln, daß die Lösungsteilchen den gleichen Schwebezustand erreichen wie der Kohlenstaub und diesen niederschlagen.As a preventive measure, it is known to prevent coal dust explosions aqueous solutions of hygroscopic salts, e.g. B. Chloromagnesium or Chlorealcium, with the addition of small amounts of a wetting agent in such a form in the air stream to nebulize that the solution particles reach the same state of suspension as the coal dust and knock it down.
Es ist auch vorgeschlagen worden, ein Löschmittel mittels elektrischer Zündung einer Sprengladung in den Streckenquerschnitt zum Ablöschen von Explosionsflammen zu schleudern. Als Löschmittel soll dabei Wasser, das einen schaumbildenden Zusatz enthält, verwendet werden.It has also been proposed to use an extinguishing agent by means of electrical Ignition of an explosive charge in the cross-section of the route to extinguish explosive flames to hurl. The extinguishing agent used is water, which is a foam-forming additive contains, can be used.
Da diese beiden Maßnahmen nur sehr schwierig durchzuführen sind, bedient man sich vorzugsweise Explosionssperren, insbesondere Wassersperren der eingangs erwähnten Art. Sie haben den Nachteil, daß ein sehr großer Wasservorrat für eine wirkungsvolle Sperre notwendig ist.Since these two measures are very difficult to carry out, served one is preferably explosion barriers, in particular water barriers of the initially mentioned type. They have the disadvantage that a very large water supply for a effective lock is necessary.
Es wurde nun gefunden, daß die Wirksamkeit dieser bekannten Explosionssperren verbessert werden kann, indem an oder in den Trögen der Wassersperre Behälter angeordnet sind, die als zweites Löschmittel Wasser entspannende und/oder bei Berührung mit Wasser Löschschaum bildende Chemikalien enthalten. Durch die Anordnung dieser Chemikalien. in Behältern, die vom Explosionsdruck zerstört werden, wird erreicht, daß sich die Chemikalien bei den langen Lagerzeiten praktisch unbegrenzt lagerfähig erhalten, um im Katastrophenfalle die beste Wirkung zu erzeugen.It has now been found that the effectiveness of these known explosion barriers can be improved by placing containers on or in the troughs of the water stop are used as a second extinguishing agent relaxing and / or on contact with water Water contain foam-forming chemicals. By the arrangement of these chemicals. in containers that are destroyed by the explosion pressure, it is achieved that the Chemicals can be stored practically indefinitely during long storage times, in order to produce the best effect in the event of a disaster.
Die Behälter sind vorzugsweise mit Wasser entspannenden Chemikalien, sogenannten Detergentien, gefüllt. Beispielsweise ist hierfür Isopropyl- oder Isobuty-Naphthalin-Sulfonsäure anwendbar. Nach einem weiteren Vorschlag enhalten die Behälter bei Berührung mit Wasser Löschschaum bildende Chemikalien wie Alkyl-aryl-Sulfonate oder Natriumoleylmethyltaurid. Löschschaum kann auch durch Gasbildner erzeugt werden, am günstigsten unter Zusatz der genannten waschaktiven Substanzen, oder z. B. auch von Karbonaten mit sauren Salzen. Es versteht sich, daß die einzelnen Explosionssperren mit Behältern bestückt sein können, die mit verschiedenen der genannten Chemikalien gefüllt sind, um die beste Wirkung zu erzielen.The containers are preferably filled with water relaxing chemicals, so-called detergents, filled. For example, isopropyl or isobutynaphthalene sulfonic acid is used for this purpose applicable. According to another suggestion, the containers contain on contact with Chemicals that form fire-fighting foam, such as alkyl aryl sulfonates or sodium oleyl methyl tauride. Extinguishing foam can also be generated by gas formers, preferably with an additive the detergent substances mentioned, or z. B. also of carbonates with acidic Salt. It goes without saying that the individual explosion barriers are equipped with containers that are filled with various of the chemicals mentioned to make the to achieve the best effect.
Die Behälter sind in Halterungen angeordnet, die aus zerbrechlichem Material bestehen. In einer Zeichnung sei die schematische Anordnung der mit Chemikalien gefüllten Behälter in den F i g. 1 und 2 gezeigt.The containers are placed in holders made of fragile Material. In a drawing is the schematic arrangement of the chemicals filled container in the F i g. 1 and 2 shown.
In F i g.1 ist am Streckenausbau 1 auf den Stützen 2 die Bühne 3 gelagert, auf der der im Schnitt dargestellte Wassertrog 4 ruht. Die Behälter 5 mit den Chemikalien sind mit Halterungen 6 an dem Wassertrog 4 befestigt.In Fig. 1, the stage 3 is supported on the supports 2 of the line extension 1, on which the water trough 4 shown in section rests. The containers 5 with the chemicals are attached to the water trough 4 with brackets 6.
F i g. 2 zeigt den Wassertrog 4 in der Draufsicht. Die Behälter 5 sind mit Halterungen 6 an den Rändern angeklemmt.F i g. 2 shows the water trough 4 in plan view. The containers 5 are clamped with brackets 6 at the edges.
